Add function avfilter_graph_parse_ptr() and favor it in place of
avfilter_graph_parse(), which will be restored with the old/Libav
signature at the next bump.
If HAVE_INCOMPATIBLE_LIBAV_API is enabled it will use the
Libav-compatible signature for avfilter_graph_parse().
At the next major bump the current implementation of
avfilter_graph_parse() should be dropped in favor of the Libav/old
implementation.
Should address trac ticket #2672.
Based on the work of Jeff Moguillansky <Jeff.Moguillansky@am.sony.com>.

Subject: [FFmpeg-devel] x11 output device for libavdevice
Date: Wed, 10 Apr 2013 23:10:47 +0000
Also disable it by default since it looks currently buggy. The
usefulness of such library is mostly limited to backward compatibility
with very old devices.

This is consistent with the rest of the file and makes listing of
emulated formats possible when ffmpeg is compiled with libv4l2.

An input channel could have been previously set with another application, like
v4l2-ctl, so if no input channel is specified use the previosly selected one.

Our previous release (1.1) contained a version 54 libavdevice
and this version here is not ABI compatible thus a bump is
needed

The current code returned a period=0, resulting in identical pts for all frames
after time-filtering. This is because AV_TIME_BASE_Q={1, AV_TIME_BASE} and
not {AV_TIME_BASE, 1}. With this patch the correct period in microseconds is computed.
struct buff_data contains a pointer to struct video_data, so passing the
file descriptor again is redundant.

In particular:
1) save errno before it (possibly) gets overwritten by other calls
2) do not forget to enqueue the buffer again in case of error

This will avoid the possibility that we dequeue more buffers than we
have obtained from the v4l2 driver.
Fixes ticket #1570

This ensures that fps and other values are estimated correctly,
the probesize also is intended to limit disk/protocol reads which
does not apply to lavfi inputs at all.
Fixes Ticket1051
Something similar could be usefull to other input devices
